\(1+\left(x-\frac{\pi}{2}\right)-\frac{1}{2}\left(x-\frac{\pi}{2}\right)^2\)

\(1+\left(x-\frac{\pi}{2}\right)+\frac{1}{2}\left(x-\frac{\pi}{2}\right)^2\)

\(1-\left(x-\frac{\pi}{2}\right)-\frac{1}{2}\left(x-\frac{\pi}{2}\right)^2\)

\(1-\frac{1}{2}\left(x-\frac{\pi}{2}\right)^2\)

\(1+\frac{1}{2}\left(x-\frac{\pi}{2}\right)^2\)
